IMPROVEMENT IN HAND-PUNCHES.

Specification forming part of Letters Patent N0. 45,'2'38, dated January 3, 1865.

To all uhom it may concern:

Be it known that I, WILLIAM NAsH, of Watertown, in the county of Jefferson and State of New York, have invented a new and usel'ul Improvement in Hand-Punches; and

- 1 do hereby declare that the following is a full,

clear, and eXact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming a part ot' this specication, in which- Figure l is a side view of a hand-punch constructed after my invention. Fig. 2 is a plan ot' the same.

Similar letters ot' reference indicate like parts.

This invention consists in applying'a movable gage to the lower limb of the punch so as to be able to punch holes in a. line with each other, and with the edge ot' the material operated upon, and also in operating the cutlfing-arm ot'- the punch by means ot' a free lever, instead of making it part of one of the handles according to the usual construction.

bis the lower, or, as it may be called, the stationary, limb ot' the punch, having two standards, o,in which is supported the Inovable or upper arm, a, of the punch. The eXtension c ot' the lower arm forms the bed-plate t f the punch. A second pair ot" standards (designated by the letter lb) rises from the bedplate c, to furnish bearings for the journals g ot' the punch-lever e. Ihe bed plate o also supports a gage composed of a plate, s, slot ted at j, to receive a clamping-screw, if, by which the plate is secured to the under side ot' the bed-plate, and of a pair of gage-plates, t', which spring up from the lower plate, s, upon each side of the bedplate, rising above its surface far enough to answer the oice ot' a gagne. A iiat spring, j', secured to the upper face ofthe bed-plate near the standards o, reaches forward and upward againstthe under surface of the punch-lever e at a point forward of its journals g, so as constantly to raise the punch n oft from the bed m of the bed-plate, and bring the opposite end of the punch-lever down upon the toe d of the upper arm, a.

The different parts of the punch may be made ot' any suitable materials, Wrought-iron being a suitable material for the punch-lever e, while the bed m should be of copper or brass. The example of my invention here shown illustrates its application for cutting or punching leather, card, and other paper, thin sheet metal, and othersubstances, which can be penetrated by a punch ot' the general description shown; but I apply it-also to cutting and punching metallic plates and othtr substances of considerable thickness by using a solid steel punch and die, the arrange ment of the parts by myinvention being such as to increase the power exerted by the operator over that exerted through a hand-punch whose punch is rigidly fixed to one ot the arms.

Having thus described my invention, I claim as new and desireto secure by Letters Patent- 1. A hand-punch for cutting leather, paper, metals, and other materials, wherein the punchlever is independent ot' the movable arm ofthe handle ofthe punch, but is operated by the toe thereof, as by a free lever not connected with the punch'lever by any joint or hinge, substantially as above'desoribed.

2. rlhe combination, with a hand-punch, of l an adjustable gage, i, substantially as and for the purpose above set forth.
